Harvest 24: Variable yields continue as wheat harvest starts
In the South West, Devon Grain store manager Duncan Lyon says it’s early days for winter wheat, although there’s very little winter barley and oilseed rape left to do.

Winter feed barley has averaged 6.2t/ha with specific weights slightly down on last year at 64.7%. “Yields have been very variable,” he adds. “Moisture has averaged 14.7% so we’ve had to dry a little bit – but not much.”
While oilseed rape has struggled, some patches have done a bit better at 3.7t/ha. “Moisture has been around 9.5% with crops averaging 44.6% oil content.”
To date (6 August) less than 10% of the expected winter wheat has come into store, with moisture contents averaging 15.3%.
“Specific weights have been around 73kg/hl, down on last year, and we’ve seen some proteins at 9% – but we’ll have a better idea in a couple of weeks’ time.”

Further north, winter barley is wrapped up and 85% of winter oilseed rape is in store, says Phil Smith, director at Western Arable Services.
“Overall, winter barley quality has been better than last year, with specific weights up to 70kg/hl and grain looking bright and golden. However, we’ve still a wide range; down to 59kg/hl.”
Yields have topped at 8.6t/ha, with moisture at 13.8-17.5%.
Oilseed rape has been hugely variable, from as low as 1.2t/ha to more than 3.7t/ha in later crops, says Phil. Crops are requiring some cleaning, but oil content has been relatively good at 44-45%.
Winter wheat is now coming into store, but it’s not quite fit – most crops in the area could do with another week.
South England
It’s a similar story in Hampshire, Wiltshire and Berkshire, where Trinity Grain has taken in around 50,000t of combinable crops so far this season – representing 25% of the expected tonnage.
Winter barley and oilseed rape are almost finished, with winter wheat and spring barley beginning to trickle in. “It’s been a relatively slow start, but the dry weather picked the pace up,” says managing director David Evans.
Oilseed rape yields have varied widely, however, oil contents are pleasing at 45%, with moisture at 9%.
Winter barley yields have also been within a wide range. “Most malting barley has met the specification, with good retention and specific weight at 63-67kg/hl.”
Planet and Laureate spring malting barley is averaging around 1.3-1.5% nitrogen.
With less than 10% of winter wheat in store so far, protein contents are close to 13%, with specific weights and Hagberg at up to 80kg/hl and over 300, respectively.

Further east, combines entered winter barley and oilseed rape a day apart, says Dewing Grain’s trading director Ian Webster. Rapeseed yields fared better for some than expected, at around 3.5t/ha and 44% oil content.
However, it’s a different story with winter barley. “It’s been demoralising,” says Ian.
“Yields have been around 6.5t/ha, which is well below the 7.75t/ha five-year average. It was drilled in good conditions and looked well but perhaps the lack of sunlight caused yields to fall short.”
Specific weights are 5kg/hl down on last year, at as low as 58kg/hl, and there are retention issues.
More positively, spring barley is performing relatively well – good quality, yielding above average, with 95% retention, specific weights of 63-64kg/hl and 1.3% nitrogen.
Combines have just entered the winter wheat, which is proving extremely variable to date.

Wheat is also under way at Eyton House Farm, Telford, but harvest got off to an uninspiring start for Isabel Udale-Moseley.
“We’ve done one very sad oilseed rape field – we lost three others to flea beetle and it was borderline as to whether we should keep it or not,” she says.
The HOLL variety managed 2.5t/ha.
Mascani winter oats, drilled late after the failed rapeseed, ranged from 4.9t/ha to 6.9t/ha, and mostly came off dry bar the headland, which was 17-18%.
“We blew it all through the drier to improve the specific weight, which is probably a bit low this year.”
Next to meet the combine was a field of Graham winter wheat, which – excepting a bare flood patch in the middle – averaged 8.9t/ha.
“We’re quite pleased with that, as there were some quite thin bits, so there must have been good bits, too,” says Isabel.
Rain overnight on 5 August pressed pause – but the remaining Graham, Typhoon, Dawsum and Extase will be ready from the weekend onwards.
“It’s looking fair to middling – there are a few weed issues, particularly ryegrass, so we’ve sprayed a couple of fields with roundup – and we might need to use a pre-emergence this autumn to get on top of that.”
